Steps to Run the Example

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run

Sample Output

Shown below is a sample output when the application is run,

Hello World!

FreeRTOS-AMP Sample Output

Attention

Output from a53ss0-1, a53ss1-0 and a53ss1-1 cores are log to the Shared memory, can be viewed via a53ss0-0 on which log reader is enabled

Shown below is a sample output on UART0 console when the application is run,
